Belt joints & joining clips

Three basic types of belt joints are offered, listed here in order of increasing joint strength:

Hardened joining clips: Riveted to the belting and linked via a connector rod.

Overlap joint: Layered over several pitches, the belt ends may consist of two or three layering steps. The ends are secured with screws and bolts. Please ask about our overlap joint options, which can include the use of flow drill plates rather than nuts and bolts.

Endlessly vulcanized joint: After the ends have been layered over several pitches, this type of joint offers the greatest degree of strength and flexibility.

For reverse drive systems or ‘S’ drives and their end rollers double-pivot belt connectors are required: A metal (pitch related) extension piece is fitted between two female joining clips, using two joining rods, to offer a flexible and smooth running of the double pivot joint over drive elements.

This metal link can also be used as a length extension repair piece, if the joining clip of one traction belting tears out.

To increase operational reliability keep the following points in mind:

The tear-out resistance of any joint remains the conveyor’s weakest point!

Any conveyor’s drive must include an overload slip clutch to help prevent joint tear out.

Use largest drive wheel option and reduce crop fall damage via a good rod covering.
